Heterogeneity and Network Structure in the Dynamics of Diffusion: Comparing Agent-Based and Differential Equation Models

Rahmandad, Hazhir; Sterman, John - In: Management Science 54 (2008) 5, pp. 998-1014

When is it better to use agent-based (AB) models, and when should differential equation (DE) models be used? Whereas DE models assume homogeneity and perfect mixing within compartments, AB models can capture heterogeneity across individuals and in the network of interactions among them. AB...

Product Differentiation on Roads: Second-Best Congestion Pricing with Heterogeneity under Public and Private Ownership

Verhoef, Erik T.; Small, Kenneth A. - 1999

We explore the properties of various types of public and private pricing on acongested road network with heterogeneous users and allowing for elasticdemand. Heterogeneity is represented by a continuum of values of time. Thenetwork consists of both serial and parallel links, which allows us to...

The Economics of Airport Congestion Pricing

Pels, Eric; Verhoef, Erik - 2003

Conventional economic wisdom suggests that congestion pricing would be an appropriate response to cope with the growing … congestion levels currently experienced at many airports. Several characteristics of aviation markets, however, may make naive … congestion prices equal to the value of marginal travel delays a non-optimal response. This paper develops a model of airport …

Inside the Queue

Verhoef, Erik T. - 2002

, based on car-following theory. The model integrates twoarchetype congestion technologies used in the economics literature …: 'static flow congestion',originating in the works of Pigou, and 'dynamic bottleneck congestion', pioneered byVickrey. Because …

Price Differentiation and Discrimination in Transport Networks

van der Weijde, Adriaan Hendrik - 2014

This paper analyzes the effects of price differentiation and discrimination by a monopolistic transport operator, which sets fares in a congestible network. Using three models, with different spatial structures, we describe the operator's optimal strategies in an unregulated market, a market...

Second-best congestion pricing in general static transportation networks with elastic demand

Verhoef, Erik T. - 1998

This paper studies the second-best problem where not all links of acongested transportation network can be tolled. The second-best taxrule for this problem is derived for general static networks, so thatthe solution presented is valid for any graph of the network, and forany set of tolling...

Congestion modelling

Lindsey, Robin; Verhoef, Erik T. - 1999 - This version: 05/11/99

Transportation researchers have long struggled to find satisfactory ways ofdescribing and analysing traffic congestion … congestion on an isolatedroad under stationary conditions. We set up the supply-demand framework usedto characterize equilibrium …
